Abstract

The utility model relates to a mechanical electronic combined door-lock with assistant unlocking device, comprising a mechanical lock and an electronic lock arranged on the fire door. The utility model is characterized in comprising a handle, a poking-sheet (2) and a slide board (3). The handle is arranged on the outside wall of the fire door; a rotating shaft (1) runs through the fire door (4), and is connected with the one end of the poking-sheet (2) which is arranged on the fire door (4) flatly. The convex column (21) arranged on the other end of the poking-sheet (2) is inserted into the corresponding hole (31) on the slide board (3) which is arranged flatly with the fire door (4). The twist parts (32, 33) are arranged on the right side and left side of the slide board (3) respectively. And in the locking state, the lower end of the one side twist part (32) is inserted into the concave slot (51) which is arranged on the lock bar board (5) of the mechanical lock; the upper end of the other side twist (33) is arranged under the armature (61) of the electronic lock (6). Comparing with the prior art, because of adopting the assistant unlocking device, at the locking state, the lock bar board of the mechanical lock is locked by the slide board which is inserted into the concave slot. Therefore, even if the main handle of the mechanical lock is rotated directly to try to move the lock bar board because of misoperation, unlocking is not achieved since the lock bar board is locked by the slide board; and the electronic lock is not affected because of misoperation.

Description

A kind of mechanical and electronic combined formula insurance lock that has auxiliary opening mechanism

Technical field

The utility model relates to is a kind ofly depositing the door latch structure that uses on the strongbox of valuables, safety cabinet or the national treasury door, particularly a kind of mechanical and electronic combined formula insurance lock that has auxiliary opening mechanism.

Background technology

The existing lockset that is used for strongbox, safety cabinet or national treasury door, generally be divided into mechanical lock and electronic lock two big classes, and adopt mechanical lock and electronic lock simultaneously is a kind of more satisfactory combination, can be spacing by the executing agency of mechanical lock, electronic lock respectively by the latch board that rotatable handles control is moved; Usually, wherein the execution unit of electronic lock is an electromagnet and reducible armature thereof, under the electromagnet power failure state, its armature or insert or embed latch board in the groove that corresponding site is provided with the lock pin of this armature interlock, make this latch board spacing, have only after confirmation such as the password of electronic lock or fingerprint, the electromagnet energising, its armature is inhaled, thereby remove locking to latch board, at this moment, can drive with key operated mechanical lock and to contract in the latch board and unblank, be design scheme " a kind of combined mechanoelectric lock " (notification number is CN2525181Y) of the utility model patent " mechano-electronic dual fail-safe coded lock " of ZL87210847.3 and our ZL02215701.8 of utility model patent formerly all provides as the patent No..But, this combined mechanoelectric lock in use, if the user just directly removed out mechanical lock before unlocking electronic lock, attempt with the direct mobile latch board of turning handle, because this moment, latch board was also by the armature of the electromagnet in electronic lock locking, therefore mobile latch board can collide, push armature, this open by mistake start do repeatedly after, electromagnet armature is damaged, thereby make whole electronic lock malfunctioning.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of mechanical and electronic combined formula insurance lock that has auxiliary opening mechanism, under its auxiliary opening mechanism effect, under the situation that electronic lock is not opened as yet, can not impact when directly opening mechanical lock and attempting mobile latch board electronic lock.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this mechanical and electronic combined formula insurance lock that has auxiliary opening mechanism comprises mechanical lock and the electronic lock that is arranged on the security door, it is characterized in that also comprising by handle, the auxiliary opening mechanism that plectrum and slide plate constitute, described handle is located on the security door outer wall, and there is a rotating shaft to pass security door, link to each other with horizontally disposed plectrum one end in security door, the other end of plectrum has a projection and inserts in the corresponding aperture on the slide plate that be arranged in parallel with security door, described slide plate has kink respectively in its left and right sides, and, under locking state, wherein insert in the groove on the latch board be arranged on mechanical lock the lower end of a lateral bending folding part, and the upper end of opposite side kink then is positioned under the armature of electronic lock.

In order to fix and better slide plate to be slided up and down in track, its top and the bottom of described slide plate are provided with the mounting hole that slide plate is slided up and down respectively.

Compared with prior art, the utility model is owing to increased an auxiliary opening mechanism, under locking state, the latch board of mechanical lock is the slide plate locking that is inserted into its groove, even if thereby this moment because of maloperation directly the main handle of rotary machine lock to attempt mobile latch board, also can be because of latch board is locked and can't open by slide plate, electronic lock then is not subjected to the influence of this maloperation at all; And when unblanking, then must first unlocking electronic lock, make its armature indentation, releasing is to the upper limit of slide plate, rotate the handle in the auxiliary opening mechanism again, make on the slide plate and carry, make the lower end of its kink leave the groove of latch board, the main handle that this moment, rotary machine was locked, latch board just can be moved and be opened the door freely.
